How do I get the spelling of the accidentals to match in the parts and score? (I’m dealing with non-transposing instruments in this case) I tried propagate properties but it didn’t do the trick.
Respelling in the score updates score and parts. Respelling in part layouts only affects the part. Therefore, if you want your respellings to carry across to the part, do them in a full score layout (which could be a new, separate one with only the relevant player in to make the process easier).
Thank you, Lillie!
